Digital information is processed for transmission in a communication system using a hidden puncturing technique. The digital information is encoded using a channel code having at least one puncturing pattern associated therewith. The puncturing pattern is preferably a rate compatible puncturing pattern. In accordance with the invention, there is no puncturing of the channel code applied at a transmitter side of the system. Instead, the resulting channel coded bits are assigned to different sections of a digital sideband or other portion of a frequency spectrum of the system, based at least in part on the puncturing pattern. The coded channel bits are then transmitted through the system in the assigned sections, and can be decoded at different code rates in a receiver of the system depending on which of the sections are used in the decoding process. By allowing different sections to be erased and the decoding to proceed at a corresponding higher code rate, the invention alleviates the effects of partial-band interference in the system.
